The VIVA LTI Tool is currently incompatible with Safari 13+. We recommend using the LTI with Chrome or Firefox while we work to fix this. We apologize for the inconvenience.

LTI Configuration:

Canvas Config URL: https://www.eduappcenter.com/configurations/nyueaf7qk6v4jab1.xml

LTI Key/Secret: contact viva@gmu.edu to obtain your key/secret 


Overview

Content Selection

The LTI tool allows any educator to browse and embed media objects alongside other content within assignments, or select content which comprises entire modules, lessons, or units. All users are able to search content added to VIVA Collections. Additionally, users can browse or search content from Group Shared Folders and personal My Items libraries.


Authentication and Account Provisioning

The tool provides automated authentication and new account provisioning, providing users with an "SSO like" experience. The LTI key/secret pair can also be configured to automatically add new users to a VIVA Group or Hub. 

LTI Tool Preview Images

Some basic preview images of the tool have been included below. More detailed instructions for using the LTI tool is available in the "Using the LTI tool" section of this guide.

Safari Login Issue

The Problem: I am using Safari and I can’t seem to login to the LTI Tool no matter what I do! I’ve even tried changing my password via reset password from email, and it still doesn’t work. 


If you are using Safari 13+ the solution below will not work, due to updates with the way 3rd party cookies are handled.  We recommend using Firefox or Chrome instead. 

 

If you are using Safari 12 or earlier: 


The Solution: 

  1. Check your cookie settings, and make sure you are allowing third party cookies. If you are strict about your cookie settings, you may need to whitelist vivaopen.oercommons.org 

  2. Close out of the LTI Tool

  3. Open the VIVA Open Homepage in a new tab 

  4. Launch the LTI tool again 


The Reason


Safari does a lot to protect your privacy, and ensure third parties aren’t tracking you without your consent. Because of this, Safari won’t allow third parties to set cookie information, if it looks like you haven’t visited the site recently. This means we can’t set an SSO cookie if you’ve recently cleared your history, are using Safari for the first time, or are using Safari on a new device. Opening the VIVA Homepage will fix this problem, because it indicates to Safari that VIVA Open is a site you use intentionally.
